We now have a CRS/C54 combo that can be offered to Customers as a "temporary exchange" should the unthinkable happen and your drive needs to be repaired by the manufacturer*. This service minimises your down time. So if you're in the market for a contra and can't make up your mind on which one, please consider this service when deciding. No other F3A drive system in the market is offering this level of support.

*Conditions apply.

This is the Ralph Schweizer Contra Rotating System (CRS) and Hacker C54 motor combo. In this configuration the Hacker C54-3D L is pre-mounted to the CRS gearbox. This item is supplied with an 85mm spinner to suit the Allure/Alchemy. We also have the spinner in 82mm in stock to suit other models.

Apart from the obvious quality, the most impressive thing with this drive is its weight. Including the C54, the weight comes in at an astounding 608 grams! This includes the full soft mount system too...

Ralph's products are of the highest quality and at the forefront of design. This CRS & motor combination is the same set-up that Wolfgang Matt is currently using in his latest designs.

Some features of the RS CRS include:

A very cool running and efficient Hacker C54 in-runner motor.

It's very easy to mount and is removed through the front of the fuselage.

Integrated soft mounting system front and rear.

Service friendly design.

All ball bearings are of the Japanese EZO brand.

Needle bearings with hardened housing and steel cages for the planetary gears made in Germany.
